Getting enough protein helps you keep strong muscles and stay mobile as you get older. This article explains why protein matters and which foods can give you the right amount.

Dr. Nguyen says protein is needed to build, keep and repair body tissues. It also helps make enzymes, hormones and antibodies. As we get older, muscle size and strength often go down, so enough protein is very important for moving well and doing daily tasks.

Dr. Nguyen adds that no single food is the best. Fish, eggs, meat and beans each give different nutrients, so you should eat a mix. Fish gives easy protein and omega‑3 fats that help the heart. Eggs have high‑quality protein with all essential amino acids and are easy to cook.

Meat provides a lot of protein, iron, zinc and vitamin B12, but Dr. Nguyen recommends lean cuts and moderate portions. Soybeans, tofu and other legumes are good plant proteins; they also give fiber and essential amino acids.
